Helium is an element with an atomic number of 2 which means that it has 2 protons in its core. So if any atom has 2 protons in its core, they it's helium no matter what.
On the periodic table of elements which I have attached in the image provided, the whole numbers in the tile tell you the number of protons. So helium is a noble gas which is found in the top right of the periodic table and I have drawn an arrow the atomic number which is the number of protons.
Answer:
Yes
Explanation:
because usually people get scared off by the word cheap.
They might think its poor quality, or something idk.
I just want points but your right :)
<span>removal of a keystone species makes the rest of the system more unstable, but the best way to understand how this works is to visualize it, either by drawing a model, or using a diagram.

Atlantic Cod is a keystone species. if the cod were removed, the seal population would decline because of a prey shortage, which would increase the populations of all the other fish species that the seals consume. Those increased fish populations would then overexploit their available prey, causing the population of prey to decline, resulting in a decline in predatory fish, resulting in an increased decline in the seal population, etc.
In addition, each increase or decrease in any species will affect every other species it interacts with, creating one hell of an unpredictable mess, which often leads to ecosystem collapse and/or extinction.
This phenomenon is known as trophic cascade.
